ABSTRACT:
A solar cell includes a silicon body with a first anti-reflection layer on its front side. The first anti-reflection layer has elongated window openings which extend parallel to one another. Parallel contact fingers made of metal extend over the first anti-reflection layer at right angles to the window openings. The contact fingers make electrical contact with the silicon body through the window openings. A second anti-reflection layer is deposited on top of the contact fingers and the first anti-reflection layer. The second anti-reflection layer reduces reflection losses at the window openings, in addition to providing further reflection protection where it overlaps the first anti-reflection layer. Highly doped zones can be provided in the silicon body beneath the window openings.
